Title: Floppy disk driver
Inventor: AKASAKI TETSUROU
IPC: G11B17/03
Filed: 1983-10-08
Abstract: PURPOSE:To prevent a co-revolution phenomenon of a hub and to secure stable revolutions of a disk by setting a larger frictional torque between a collet and a collet lever than that between a hub and a hub holder. CONSTITUTION:When a floppy disk 16 is stored, a hub 14 is pressed by a collet 17 pressed by a collet lever 18. Then a projection 17a and a drive shaft 15 are fitted to the guide grooves 14c formed on both sides of the hub 14 respectively. Therefore the disk 16 is chucked, and both the hub 14 and a hub holder 13 are revolved in a body by the shaft 15 when a main shaft 11 is revolved. The frictional torque between the collet 17 and the lever 18 is set larger than that between the hub 14 and the holder 13. This prevents a co-revolution phenomenon of the hub 14 and secures the stable revolutions of the disk 16. Then the synchronous revoltuions are obtained between the collet 17 and the hub 14 with reduction of a disk loading position shift. Thus the chucking accuracy is improved.

Title: Feature extracting method
Inventor: NAGATA MASAHARU
IPC: G06K9/52
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To provide the feature extracting method which can evade a decrease in a recognition precision caused by noise. SOLUTION: A character frame 46 is scanned in a line width direction to detect a pair of a white-black change point and a black-white change point on a scanning line, and the midpoint between those change points is found. Then the character frame 46 is divided into I×J cell areas and the cumulative number of midpoints in the cell area where the found midpoint is present is counted. This counting is carried out individually by the cell areas. The cumulative number of midpoints of the respective cell areas at the point in time when the scan on the entire surface of the character frame 46 is completed is used as a matrix element to generate a feature matrix.  When the isolation distance H between the pair of white-black and black-white change points is less than a threshold T, it is decided that a change point which is at the distance H is a change point of noise N and this point is not counted; when the isolation distance H is larger than the threshold T, it is decided that the change point at the distance H is a change point of a character line part to be recognized, and the cumulative number of midpoints is increased by one. Therefore, the addition of a midpoint of white-black and black-white change points of noise N to the cumulative number of midpoints as a feature quantity can be evaded.
